NNVT 16mm Gen 2+ Lightweight Image Intensifier Tube (GT6680)

The GT6680 is a high-performance 16mm Super Gen 2 (S25+ photocathode) image intensifier tube designed specifically for modern lightweight night vision systems and specialized optical applications. By combining a compact 16mm format with advanced micro-channel technology, it delivers exceptional low-light performance while drastically reducing overall system weight.

Key Technical Highlights

  • Revolutionary Weight Reduction: Slashed from ≤ 80g down to ≤ 50g (a 37.5% reduction). This drastic trimming minimizes operator neck fatigue during extended missions, making it the ultimate drop-in solution for weight-sensitive platforms without sacrificing performance.

  • Uncompromised 40° Field of View (FOV): Designed for full optical compatibility, the 16mm format seamlessly pairs with specially engineered 16mm objective and eyepiece lens assemblies—already offered by leading optical manufacturers—allowing integration into compact housings while maintaining a full, zero-loss 40° field of view.

  • Flexible FOM Parameters:

    • The initial production batch features a robust baseline of FOM 1600.

    • Subsequent product lines will comprehensively cover a full spectrum of higher FOM tiers to accommodate diverse operational budgets and mission profiles.

  • Dual Phosphor Options: Available in both high-efficiency P43 Green Phosphor (for classic high-contrast visual clarity) and P45 White Phosphor (for modern crisp grayscale imaging and reduced eye strain).

  • Superior Optical Performance:

    • Signal-to-Noise Ratio (SNR): Min. 25

    • Resolution: Min. 64 lp/mm

    • Integral Sensitivity (2856K): Min. 700 µA/lm (S25+ high-response photocathode)

  • Fiber Optic Inverter & Auto-Gating: Equipped with a precision fiber optic inverter for crisp image orientation and an integrated auto-gating function (gate width > 420ns) to protect the tube under sudden bright-light fluctuations.

  • Standard Electrical Interface: Utilizes a reliable 3-pin electrical interface housed in a durable body, ensuring seamless integration into standard 16mm compatible housing architectures.

Target & Next-Gen Applications

  • Lightweight Tactical Systems: Ultra-light monoculars and binoculars (MX-10160 format adaptations).

  • Advanced Thermal-Optical Fusion Systems: Next-generation multi-spectral fused goggles (such as ENVG-style architectures) that combine low-light analog video with thermal imaging layers, where strict spatial and weight budgets are mandatory.

  • Smart Networked & AI-Enabled Optronics: Advanced tactical systems integrating real-time communication data feeds, augmented reality (AR) HUD overlays, and edge-AI assisted target recognition, where every gram saved on optical components is critical to reducing combat load.
